Said formers d have dovetail ribs e on beating out boot and shoe soles embodying their upper surfaces, which are inserted in our invention. Fig. 2 represents a sectional dovetail slots formed in blocks or holders f. i5 view of a portionof themachine,showingone Said blocks f have convex upper surfaces, 95 of the jacks, one of the molds or formers, and which are fitted upon concave seats formed y the means for pressing the last on the jack on the levers h, studs or bolts g, passing against the mold or former. Fig. 3 represents through slots in the blocks f into the levers a section on the plane of line 3 3,Fig. 2. Fig. 71 connecting the molds or formers d to the 5o 4 represents a side elevation of the devices levers, the convex surfaces of the blocks f Ioo and the concave seats on the levers h permitting the blocks and the molds or formers to slide slightly in any desired direction, so that the molds or formers are permitted to tip sufficiently to accommodate themselves to the bottom of the sole which is pressed against them, thereby giving a uniform pressure to all part-s of said bottom. The niolds or formers CZ are permitted to yield slightly to upward pressure against them by means of springs 23, interposed between collars 24, bearing against the inner ends of the levers 71., and a support 22, which is afiixed to and forms a part of the rotary supporting-frame. A rod 2l, affixed to the support 22, passes through the spring 23 and through enlarged orifices formed in lever 71. and collar 24, said rod having a nut or enlargement above the lever h and preventing the lever from swinging downwardly at its outer end beyond a certain limit. The spring 23 is sufficiently powerful to prevent the lever h and mold or former d from yielding too freely, said mold yielding only to extreme pressure, such as would be caused by variations in the thickness of the soles being pressed.

0n the shell or casting c, between the upper and lower ends thereof, are formed a series of tubular bosses or sockets k, in which are fitted vertically a series of cylindrical plungers m, which are adapted, as hereinafter described, to impart upward movement to the lasts supporting the boots or shoes to be treated and press the soles of the boots or shoes on said lasts against the molds or formers d. Each plunger has at its lower end ears s s, which receive a rod or pivot q, forming a bearing for the upper end of a link o, which constitutes one member of a vertical togglejoint, the other member of which is a link p, bearing upon a rod or pivot r, supported by ears t t, affixed to the gear b, constituting the base of the rotary frame. The meeting ends of the links 0 19 are fitted upon trunnions u u, which are formed upon a casting or holder e, in which is journaled upon a vertical axis a wheel or roller x. Said wheel or roller bears upon the perimeter of a horizontal cam 20, which is rigidlysupported, so that it does not rotate with the frame above described. rlhe casting or holder c is provided with a horizontal arm w, in which is journaled a vertical stud supporting a wheel or roller y, arranged to act upon the inner perimeter of the cam 20, as shown in Figs. 2 and 10. Said cam has at a given point on its inner perimeter an inwardly-projecting or thickened portion 20', which acts upon rollers y when they are brought in contact with said port-ion and draws back the holder or casting e and the meeting ends of the toggle-links 0 23 thus throwing said links out of alignment, as shown in Fig. 2, and causing the depression of the plunger m to its lowest point. The cam 2O is formedat 2l to permit the wheels or rollers a: to move inwardly or toward the center of the cam, and thereby enable the links of the toggle-joint to assume the position last described. The cam is formed at 22 to throw the holder or casting v outwardly, and thereby move the toggle-links into line with each other,or approximately so, for the purpose of raising the plunger m, and thereby causing it to press a last against the mold or former CZ above said plunger, as hereinafter described. The cam 2O has another peripheral enlargement 23',- which gives an additional movement to the toggle-links, and thereby increases the upward pressure of the last against the mold or former (Z. The rollers y and the internal projection 20 constitute a positive means for drawing back themeeting ends of the toggle -links, and are substitutes for a spring which might be arranged to act on the meeting ends of the links to draw the same backwardly when the contour of the perimeter of the cam 2O permits.

It will be seen from the foi-going that when the rotary frame carrying the series of plungers and molds or formers is rotated the fixed cam alternately raises and lowers the plungers by its action on the toggle-joints supporting said plungers, so that each plunger is depressed upon reaching a given point of the frame and raised after passing said point. Rotary motion is imparted to the frame by means of a pinion b3 upon a vertical shaft b4, which is rotated by a suitable connection with a driving-shaft, the pinion b meshing with the gear b, as shown in Fig. 1.

In connection with the mechanism above described we employ a series of jacks, each of which is of telescopic construction, so that it can be extended and contracted vertically, and carries at its upper end a last 13, and-is pivoted at its lower end, at 5, to ears 6, rigidly affixed to the base or gear wheel b. The telescopic construction of the jack is secured by making it in two parts or sections-namely, the lower section 4, which is pivoted to the ears 6, and the upper or sliding section 7, which is a cylindrical rod adapted to rotatein bosses or bearings 17 17, formed on the section 4, and also to move lengthwise in said bearings. To the upper end of the vertically movable and rotatable section 7 is attached a plate 12, having studs 1414, which are engaged with sockets formed in the shank of the last 13, and secure said last to the plate l2.

p represents a guide attached to or formed on the plunger m. In said guide is a collar 15, having a flange at its upperend projecting over the upper edges of the guide p', said collar being rigidly attached to the section 7 of the jack, so that as the plunger m rises and falls it will by its engagement with the collar 15 raise and lower with it the upper section 7 of the jack and the last 13, carried thereby.

From the foregoing it will be seen that the last is capable of the following motions while engaged with the jack, namely: It can be swung from the position shown in full lines in Fig. 2 to the position shown in dotted lines in said figure by a movement of the entire jack IOO IIC)

upon its pivot and by a partial rotation of the upper section 7 in the bearings formed for it onthe lower section 4,thesetwo movementsnamely, the inward swinging movement of the entire jack and the partial rotation of the upper section thereof-bringing the plate 12 over t-he corresponding plunger m and bringy ing the last into position to co-operate with the corresponding mold or former d; secondly,`an upward movement with the plunger m, said movement being partaken of by the last, the plate l2, and the upper section 7 of the jack, independently of the lower or pivoted section, the latter having no upward movement. Thelast is thus brought into such position that a slight upward movement will bring the outer surface of the sole of the boot or shoe thereon into contact with the mold or former cl, the arrangement of the parts being such that when the plunger m is in its normal position there is room between its upper end and the corresponding mold or former to swing the last and the boot or shoe thereon freely to place under the mold or former without contact between the sole and the pressing-surface of the mold or former.

Means are provided for giving the plunger an upward movement by muscular power exerted by the operator, so as to bring the upper surface of the sole to a bearing on the under surface of the mold or former, so that when the power-pressure is applied said pressure will be the same whether the sole be thicker or thinner. The said hand pressing means are as follows: The plunger m is made in two sections, one of which includes the lower end of the plunger and the ears s s thereon, while the other includes the upper end of the plunger, upon which the jack-plate l2 bears. The upper section bears upon the lower and is adapted to be rotated independently, the meeting ends of the two sections being made spiral, the upper section having a spiral lower end 2,while the lower section has a spiral upper end 3, as shown in Figs. 4, 5, and 6. It will be seen, therefore, that by rotating the upper section upon the lower, the latter being incapable of rotating, the upper section will be either raised or lowered bythe movement of one spiral end upon the other, accordingly as the upper section is rotated in one direction or the other, the rotation of said upper section in one direction causing it to rise,

while a rotation in the opposite direction causes it to fall in the socket lo. The upper section is provided with a handle 27, whereby it may be rotated for the purpose described. The handle is here shown as applied to a split ring 25', encircling the upper end of the plunger, and. having lugs or ears, which together form a cylindrical `shank having a screwthreaded portionv lat its outer end engaged with an internally-threaded socket in the handle 27 and a conical or wedge-shaped portion 26', on which bears a correspondingly-shaped internal surface in the handle 27, the arrange mentdbeing such that when the handle 27 is turned to screw onto the threaded portion 26 its wedge-shaped inner surface will compress the shank 25 and the ring 25, thereby causing the latter to bind upon the plunger m and lock said ring and the handle thereon to the plunger, with thev handle projecting in any desired horizontal direction, so that the handle may be moved back to take anew hold.

Within the plunger' m is a sleeve m', the upper end of which has a horizontal tiange fn', which has a downwardly-prog ecting lug or rib o', on which are formed ears o2, which bestride a vertical rib or guide 03, formed on the exterior of the shell or casting c, the'sleeve m being prevented from rotating by the engagement of the lugs or ears o2 with the said rib 03. The sleeve m therefore rises and falls with the yupper section of the plunger when the latter is rotated, but does not rotate with said upper section.

8 represents a split ring fitted in an annular socket between the upper portion of the plunger and the sleeve m', said ring encircling the sleeve and being adapted to be compressed thereon. 9 represents a ring composedof .several segments having beveled outer surfaces bearing on a beveled seat l0, formed in the upper portion of the plunger m, as shown in Fig. 2. The flange n of the sleeve m rests upon the ring 9, and by its downward pressure on said ring causes the segments thereof to slide inwardly down the inclined seat 10, and thus exert an inward pressure on the split ring 8, whereby said ring is contracted and caused to bear against the periphery of the sleeve m', the result being the locking together of the plunger and the sleeve m whenever the last is pressed against the mold or former d with sufficient pressure. to depress and hold the wedge-shaped segments of thering 9 in position to compress the ring 8. It will be seen, therefore, that when the operator has raised the last by a partial rotation of the upper section of the plunger, and has thereby brought the upper surface of the sole to a bearing on the mold or former d, the downward pressure exerted upon the wedge-shaped sections of the ring 9 by the conta-ct of the sole with the mold or former will compress the ring 8, and thereby lock the upper section of the plunger to the non-rotating sleeve m', thereby preventing the upper section of the plunger from rotating backwardly and being thereby depressed. The last is therefore held automatically at the point to which it is raised by the rotation of the upper section of the plunger until the pressure of 'the mold or former is removed from the sole, the removal of said pressure releasing the wedge-shaped sections of the ring 9 and permitting the split ring S to eX- pand sufciently to release its hold upon the` sleeve m', whereupon the upper section ofk the plunger is free to rotate, and is partially rotated by gravitation back to its depressed or starting point, the incline 2 being formed roo IIO

removingthe bottom of the boot or shoe from the mold or former with which it was in contact, the released jack being thus permitted to swing outwardly on its pivot 5, as indicated at the left of Fig. 1 and in full lines in Fig. 2.`

The jack in swinging outwardly assumes an inclined position., so that the last and its supporting-plate l2, which are located, mainly, at

one side of the upper section 7 of the jack, turn automatically or by gravitation to a position substantially at right langles with the Aposition they occupy when the sole is `under pressure, the last being thus brought to the position shown in Fig. .2, with its toe projectngaway from the machine,so that vthe operator can conveniently remove the booter shoe therefrom -and apply another. .After `the applicationof another boot or shoe to the released jack the operator swings said jack inwardly and partially rotates the upper section to bring the last into line with the cor- 1 responding mold or former, and then byapartial rotation of the upper section of the plunger raises the last until the sole thereon comes to a bearing on the mold or former above it. The operator then by depressing a treadle 253 sets the driving mechanism in motion and `causes the supporting-frame to rotate until the roller connected with the toggle-joint supporting the plunger corresponding with the jack under consideration, reaches the portion 22 of the cam 20, and is thereby straightened and caused to raise the said plunger by the power ofthe machine, and thereby subject the sole on the last supported by said plunger tothe power-pressure. The same rotation of the supporting-frame brings another jack to the point where its supporting-plunger is released, as above described, and when thelastmentioned jack reaches said position the rotation of the supporting-frame is automatically stopped by any suitably-organized stopmotion, which need` not be necessarily described here. The operator removes the completed boot or shoe, as before, and applies another, and replaces the last of the jack under its moldor former and upon its plunger and again starts the supporting-frame in motion, and so on, each last being released upon reaching the part 21 and pressed upwardly upon reaching the part 22. The upward pressure is increased by the part 23 of the cam 20, and the increased pressure is maintained until the part 21 of the cam commences to act in releasing the pressure. The upper section7 of each jack has a collar 18, to which is attached the lower end of a spring 16, interposed between said collar and the `upper `bearing 17, the upper end of said spring being engaged with said bearing on the lower section 4 of the jack. Said spring facilitates the partial rotation of the upper section of the jack when the upward pressure exerted on the last is removed.

19 represents a flange or collar attached to collar 18, having one side iat, said fiat side bearing upon one side of the lower section 4 of the jack and preventing the collar 18 from rotating.

We prefer to make each section of the plunger m double-that is to say, with an inner and an outer shell, the inner shell of the rotatable upper section having a spiral end .2', while the inner shell of the lower section has a corresponding spiral end 3, as shown .in Fig. 2. The highest portion of the spiral end 3 is at the opposite side of the plunger from thehighest portion of the spiral end 3, 4so that when the upper `section of the plunger has been rotated so that the lower portions of its spiral ends 2 2 rest on the higher portions of the spiral ends 3 3 said section will be supported at opposite sides of its center, so that it will not :have atendency to tip to one side.

The two-part plunger here described `may be variously modified in construction without departing from the spirit of our invention. For example, the lower section of the plunger may be formed as a `nut and the upper section as a screw adapted to engage said nut, the internal non-rotating sleeve m and the automatic locking devices to prevent the backward rotation of the upper section of the plunger being substantially the same as above described. By making the cam 20 in steps, as .22 23', so as to increase the pressure from point to point, we are enabled to do better work than .if the cam were formed to apply the maximum pressure at once. There may be `any desired number `of said steps, as two or more.
